did not get touch pen and have to buy one and it is absolutely needed . or else, easy to install and buy a cover also ;) bought a frame with fan and shaped to fit the LCD and easy to take off the fan and top cover (see pictures)
Bought two of them, both are not working, Tried it with a Pi zero w, Pi 3A+ and Pi4 with fresh Raspbian and Kali images. Tried the driver installation for LCD35-show and MHS35-show, even the preconfigurated images from Goodtft did not work. All i get is a Whitescreen. Maybe the customs authority xrayed them to death maybe the product is just bad quality.. my experience.
